To all whom it may concern:

Be it known that I, ALEXANDER BERN- HARD DRAGER, a subject of the German Emperor, and resident of Liibeck, Germany, have invented new and useful Means for Distributing Oxygen, of which the following is a specification.

The present invention relates to a plant for distributing oxygen in a number of compartments or rooms, which may be adj acent but which may be separated from one another and more particularly in a number of rooms or compartments of submarineboats, torpedo-boats and the like.

In distributing oxygen in compartments, which generally or under certain circumstances cannot be filled with atmospheric air, it is highly important when a leakage occurs in the pipes which will happen in spite of the greatest precautions that the supply of oxygen to all rooms or compartments occupied by human beings is not interrupted or does not fail. It is also of the same importance that, when any room is inaccessible either from water or from poisonous gases, vapors or the like or from other causes, the supply be not hindered. These objects will be attained according to the present invention by arranging the reservoirs such as steel flasks filled with highly compressed oxygen in groups and by conducting a special main pipe from each. group to all the compartments wh ch are to be supplied. Every main is provlded n every room that is intended to be occupied by human beings with a tapping piece or with means for drawing off, to enable'any person to take oxygen rom any main pipe in any room. When any pipe becomes leaky only one fraction of the quantity of 0x gen in store will be lost, while the rest 0 the quantity will remain at free disposal. The occupants of the rooms are in this case as well as in such cases in which single rooms are inaccessible, well able to save them-' selves.

In the accompanying drawings-Figures 1, 2 and 3 are sectional diagrammatical views of a submarine boat, illustrating three difierent arrangements of distrib uting plants embodying my invention. Fig. 4 is a detail view of an emergency tapping place on a larger scale. Fig. 5 is a cross section of a submarine boat in a perspective View. Fig. 6 is a controlling apparatus for controlling the amount of oxygen in the difl'ereritgroups. Figs. 7 andl 8 ,aresimilar viewsto Figs. l'and Y Y. v

In the arrangement shown-in Figfl two groups of oxygen flasksza are used, leach group consisting of three-flasks by :way of example. For each group there is one main pipe 6 running through thej whole length-10f the boat. Each main. is provided in every compartment with a. secondaryor emergencytapping'device 03, shown in detail in F1g.' i. When the compartments are in communication one with the other, the oxygen may be supplied 'tolthem bythe main tapping device 0, while the emergency tapping devices will be used when the particular lionzpartment is cut oil from the rest of the oa I If desired means may be provided for supplylng oxygen from outside. To this end by way of example the main tapping device 0 may be connected with a pipe which extends through the wall of the boat and is provided with a shut of! cock 6 or the like on the inside of the boa The arrangement shown in'Fig. 2 differs from that shown in Fig. 1, by distributing the differentflasks in the different chambers, carebeing-taken to properly balance or distribute the weight. In this plant it Wlll be easy to place the flasks where they are out of the way.

In the plant shown Fig. 3 the oxygen flasks are distributed in three groups and therefore'there are also three mains J).

In the plant shown in F ig; 5 two mains b are used, the'j-flasks a being accommodated at the lowest'part of the boat. In this plant a special indicating apparatus i is used,

which is shown in detail in Fig. 6. [This apparatus comprises two pressure gages m and m havlng besides the usual pointer g a second pointer 72. which is not connected with the pointer 9 but which can be moved by hand. Thus when the pointer h is placed over the pointer g at ordinary pressure it will be at once noticed, when there is a leakage in one of the mains. Thus the position of the pointer g on the gage m indicates that the pressure has fallen considerably and from the dial is it will be seen, that there is a leakage in the main I or in one of the flasks belonging to the corresponding groups, while oxygen can only be taken from the main II. The plants shown in Figs-7 and 8 differ from those shown in Figs. 1 and 3 only in so far as the emergency-tapping devices (Z are concerned. In these modifications there is only one outlet nozzle d which is in connection with the mains by branch pipes having cocks (Z I claim:

1. In a plant for distributing oxygen in a casing having a plurality of compartments, a plurality of oxygen reservoirs in the casing, main pipes leading from the respective reservoirs and running through all the compartments, and a tapping device in each compartment for each main pipe.

2. In a plant for distributing oxygen in a casing having a plurality of compartments, a plurality of oxygen reservoirs in the easing, main pipes leading from the respective reservoirs and running through all the compartments, a tapping device in each compartment for each main pipe, and an indicating apparatus for indicating the pressure in the main pipes.

3. In a plant for distributing oxygen in a casing having a plurality of compartments, a plurality of oxygen flasks in the casing distributed in groups, a plurality of main pipes corresponding in number to the groups, each main pipe connected to the flasks of one of the groups and running through all the compartinents, and tapping devices in each compartment on the respective main pipes.

4. In a plant for distributing oxygen in a casing having a plurality of compartments, a plurality of oxygen flasks in the casing distributed in groups, a plurality of main pipes corresponding in number to the groups, each main pipe connected to a different group of flasks and running through all the compartments, a main tapping device for each main pipe, and an emergency tapping device in each compartment 011. each main pipe.

5. In a plant for distributing oxygen in a casing having a plurality of compartments, a plurality of oxygen reservoirs in the easing, main pipes leading from the respective reservoirs and running through all the compartments, tapping devices in each compartment on the respective main pipes, means for indicating the pressure in the main pipes, a single outlet nozzle connecting the members of each group of tapping devices, and cocks intermediate each outlet nozzle and the respective main pipes.
